Before you begin, please see our compatibility matrix to find out if this version of the product is fully tested on Linux or OS X.
Follow the instructions below to install EMM on Linux or OS X.
Install the required applications
- Establish a SSH connection to the Linux machine or log in on the text Linux console. You should either log in as root or obtain root permissions after you log in via the
su
orsudo
command. - Be sure your system meets the prerequisites. Java Development Kit (JDK) is essential to run the product.
Installing EMM
- If you have not done so already, download the latest version of the product as described in Downloading the Product.
Extract the archive file to a dedicated directory for the product, which will hereafter be referred to as
<PRODUCT_HOME>
.
Setting JAVA_HOME
You must set your JAVA_HOME
environment variable to point to the directory where the Java Development Kit (JDK) is installed on the computer.
Environment variables are global system variables accessible by all the processes running under the operating system.
- In your home directory, open the BASHRC file in your favorite Linux text editor, such as vi, emacs, pico or mcedit.
Add the following two lines at the bottom of the file, replacing
/usr/java/jdk1.6.0_25
with the actual directory where the JDK is installed.On Linux: export JAVA_HOME=/usr/java/jdk1.6.0_25 export PATH=${JAVA_HOME}/bin:${PATH} On OS X: export JAVA_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Save the file.
If you do not know how to work with text editors in a Linux SSH session, run the following command:
cat >> .bashrc
Paste the string from the clipboard and press "Ctrl+D."
To verify that the
JAVA_HOME
variable is set correctly, execute the following command:On Linux: echo $JAVA_HOME On OS X: which java If the above command gives you a path like /usr/bin/java, then it is a symbolic link to the real location. To get the real location, run the following: ls -l `which java`
Setting system properties
If you need to set additional system properties when the server starts, you can take the following approaches:
- Set the properties from a script
Setting your system properties in the startup script is ideal, because it ensures that you set the properties every time you start the server. To avoid having to modify the script each time you upgrade, the best approach is to create your own startup script that wraps the WSO2 startup script and adds the properties you want to set, rather than editing the WSO2 startup script directly. - Set the properties from an external registry
If you want to access properties from an external registry, you could create Java code that reads the properties at runtime from that registry. Be sure to store sensitive data such as, username and password to connect to the registry in a properties file, instead of in the Java code and secure the properties file with the secure vault.
SUSE Linux
When using SUSE Linux, it ignores /etc/resolv.conf
and only looks at the /etc/hosts
file. This means that the server will throw an exception on startup if you have not specified anything besides localhost. To avoid this error, add the following line above 127.0.0.1 localhost
in the /etc/hosts
file.
<ip_address>
<machine_name> localhost
